Abstract : The characteristics of a newly devised high energy output battery are described. This battery utilizes aluminum and chlorine as the reactive materials. The electrochemical reactions take place in a molten salt electrolyte maintained at 125-200C. The properties of this battery are compared with a list of desired characteristics of high energy batteries, and are contrasted with those of existing conventional batteries and advanced batteries now under development. Studies of the aluminum electrode revealed an unexpectedly high cell voltage arising from concentration differences in the electrolyte. This voltage increment can be added to the voltage expected from the aluminum chlorine cell, and yields a 25 percent increase in theoretical energy output. A model of the electrolyte structure is postulated which explains the unusually high voltages. This model provides a guide for the prediction of still other electrodes and electrolytes that might be utilized in high energy output batteries. (Author)
